Having two identical alleles for a particular gene.

NGSS.HS-LS3-2

The physical characteristics of an organism; the expressed trait for a gene.

• Complete dominance

• Phenotype

• Heredity

• Gene

Tags

NGSS.HS-LS3-1

A gene that can be masked by a dominant gene.

• Recessive

• Law of segregation

• Law of independent assortment

• Complete dominance

Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.

• Codominance

• Punnett Square

• Genetic Cross

• Law of independent assortment

Parental genes are randomly separated into the gametes; they contain only one gene of the pair. Offspring therefore only inherit one allele from each parent.

• Genetic Cross

• Punnett Square

• Complete dominance

• Law of segregation
